文摘

•: The afterglow of the SrAl₁₄O₂₅:Eu²⁺, Dy³⁺ was improved, doped with moderate Er³⁺.
•: The structures of phosphors were characterized by XRD, TEM, HRTEM, FT-IR, and XPS.
•: The luminescence properties of phosphors were systematically analyzed.
•: The absorption in the visible region was increased with Er³⁺ doping in moderation.
•: The enhancing mechanism of Er³⁺ on the luminescent properties was analyzed.
